[Q]: Passage: The principle of faunal succession is based on the appearance of fossils in sedimentary rocks. As organisms exist at the same time period throughout the world, their presence or (sometimes) absence may be used to provide a relative age of the formations in which they are found. Based on principles laid out by William Smith almost a hundred years before the publication of Charles Darwin's theory of evolution, the principles of succession were developed independently of evolutionary thought. The principle becomes quite complex, however, given the uncertainties of fossilization, the localization of fossil types due to lateral changes in habitat (facies change in sedimentary strata), and that not all fossils may be found globally at the same time. Question: Which principle is based on the appearance of fossils in sedimentary rocks?
[A]: The principle of faunal succession


[Q]: Passage: The historian Frederick W. Mote wrote that the usage of the term 'social classes' for this system was misleading and that the position of people within the four-class system was not an indication of their actual social power and wealth, but just entailed 'degrees of privilege' to which they were entitled institutionally and legally, so a person's standing within the classes was not a guarantee of their standing, since there were rich and well socially standing Chinese while there were less rich Mongol and Semu than there were Mongol and Semu who lived in poverty and were ill treated. Question: There were many Chinese with what unexpected status?
[A]:
rich and well socially standing
